A field emission device includes a non-stabilized special vector electron source having a field emission edge emitter cathode (102), a stabilizing anode (103) and a current stabilizer (104) in electrical circuit of the stabilizing anode (103), a collecting anode (105) and at least one control electrode (106) for controlling emission flow of electrons from the vector electron source to the collecting anode (105).
